    Market and Liquidity Risks Using Transaction-by-Transaction Information
    (MDPI, 2021-07) González Sánchez, Mariano; Ibáñez Jiménez, Eva María; Segovia San Juan, Ana Isabel
    The usual measures of market risk are based on the axiom of positive homogeneity while neglecting an important element of market information—liquidity. To analyze the effects of this omission, in the present study, we define the behavior of prices and volume via stochastic processes subordinated to the time elapsing between two consecutive transactions in the market. Using simulated data and market data from companies of different sizes and capitalization levels, we compare the results of measuring risk using prices compared to using both prices and volumes. The results indicate that traditional measures of market risk behave inversely to the degree of liquidity of the asset, thereby underestimating the risk of liquid assets and overestimating the risk of less liquid assets.

    Causes of country-specific effect related to the value relevance of cash flows and earnings: evidence from France, Germany, Italy and Spain
    (Taylor & Francis, 2022-09) González Sánchez, Mariano; Ibáñez Jiménez, Eva María; Segovia San Juan, Ana Isabel
    Previous studies show that, in common-law countries, the explanatory power of stock returns is higher using cash flows than earnings and accruals, while the opposite is true in code-law countries. Moreover, the literature has shown the existence of a country-specific effect motivated by different causes (taxation, financial system, creditor protection, among others). Our aim is to analyze whether this country-specific effect exists among companies in the largest Eurozone countries (France, Germany, Italy and Spain) despite the common regulatory framework, and also to study the causes that explain this country effect. We find empirical evidence that French, Italian and Spanish firms are influenced by tax rules, while German companies are more affected by creditors protection; also, Spain presents a bank-oriented financial system. Besides, the transitory earnings effect, characteristic of code-law countries, is not a cause of the country-specific effect. Therefore, national regulations are more relevant than the general EU regulatory framework.

    Board of Directors’ Remuneration, Employee Costs, and Layoffs: Evidence from Spain
    (MDPI, 2021-07) González Sánchez, Mariano; Ibáñez Jiménez, Eva María; Segovia San Juan, Ana Isabel
    Most of the empirical studies on board remuneration have focused on finding explanatory performance measures. There are studies that analyze if the compensation contracts of directors reward managers in such a way that they strive to maximize firm performance and shareholders’ wealth; however, there are few studies on the social aspect of corporate governance, or agent–employee and principal–employee relationships. Thus, in this study, our aim is to test whether there is a causal relationship between the remuneration of the board of directors of listed companies and the personnel policies of the companies, expressed through the cost of personnel and layoffs. For that, we used a sample of Spanish listed companies, and we found that two performance measures (return on equity and earnings per share on market price) have a greater effect on the growth rate of board remuneration when layoffs occur. Additionally, we found that the sales revenue and cash flow on total assets subsequently influenced personnel management.

    Market and model risks: a feasible joint estimate methodology
    (Springer Link, 2022-03-01) González Sánchez, Mariano; Ibáñez Jiménez, Eva María; Segovia San Juan, Ana Isabel
    The increasing complexity of stochastic models used to describe the behavior of asset returns along with the practical difficulty of defining suitable hedging strategies are relevant factors that compromise the soundness and quality of risk measurement models. In this paper we define the risk model as the mispricing a consequence of using an inadequate model to describe asset behavior and we develop a least-squares Monte Carlo methodology to estimate market and model risk simultaneously. The results show that at different confidence levels and time horizons the proposed methodology to estimate the market and model risks has a greater joint explanatory power than the isolated estimate of market risk.
